/** @file
 * Multiple PHP Versions test
 * 
 * This file tests HTML Purifier in all versions of PHP. Arguments
 * are specified like --arg=opt, allowed arguments are:
 *   - exclude-normal, excludes normal tests
 *   - exclude-standalone, excludes standalone tests
 *   - file (f), specifies a single file to test for all versions
 *   - xml, if specified output is XML
 *   - quiet (q), if specified no informative messages are enabled (please use
 *     this if you're outputting XML)
 * 
 * @note
 *   It requires a script called phpv that takes an extra argument (the
 *   version number of PHP) before all other arguments. Contact me if you'd
 *   like to set up a similar script. The name of the script can be
 *   edited with $phpv
 * 
 * @note
 *   Also, configuration must be set up with a variable called 
 *   $versions_to_test specifying version numbers to pass to $phpv
